Durable task flows, managed children, sticky cancel, and api.runtime.taskFlow for plugins.
Task Flow substrate & plugin API
v2026.4.2 restores the core Task Flow substrate with managed vs mirrored sync modes, durable flow state and revision tracking, and openclaw flows primitives for inspection and recovery — separate from plugin authoring layers.
Managed child task spawning plus sticky cancel lets orchestrators stop scheduling immediately while parents settle to cancelled after children finish.
Plugins receive api.runtime.taskFlow so trusted code can create and drive flows from host-resolved OpenClaw context without passing owner identifiers on every call.
